So far this is what I got for wireguard with mullvad:

my isp: KPN
hardwired:yes
country: Netherlands
speeds:
up: 200mb/s (I get easily 300-400mb/s but this might be related due to the overhead they sent me I
expect after 200mb/s the advertised speed, the upload gets unstable so I just would keep it on
200mb/s.

down: 204mb/s (this is accurate)

for NL:
Mullvad NL22:

for FR:
Mullvad FR15:

for US:
Mullvad US172:

for AUS:
Mullvad AUS11:

for Singapore:
Mullvad SG4:

the first few speedtests are countries close around my current location, the other ones are really far away :), though I’m still amazed about the performance I get and when I watch other results from other people here, I think my wireguard speed could even go higher but its bottle necked by my isp.
